Yea, I highly doubt any company does an actual hand wax job (that's what she said). Machine waxes. I call out Burton because they have excellent bases. Their sintered bases run pretty fast even with little wax on it. I find Burton boards to ride better new compared to competitors.
I'm not against waxing new boards. I just think most of those concerned with it don't actually do enough to get that much of a performance difference.
If you're just resort riding, my guess is that you're going to be fine riding factory. But like I said, there are brands that do suck factory waxed, I don't argue that.
If you're going on a trip without a waxing kit, then I would wax then too. I just don't paint all factory wax with a broad brush stroke.
Edit: Do you really sharpen your edges after each ride?
